MOP.

Application filed September 9, 1922.

To all whom it may concern:

Be it known that I, HAswnLL A. SwAsnY, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Mop, of which the following is a specification.

This invention relates to brushing and scrubbing, and more particularly to floor mops of the type known as dry hand mops.

The object of the invention is to provide a mop of this character so constructed that it may be wrung dry without wetting the hands, which is self wringing and self rinsing and which may be used as a scrub mop in addition to performing the functions of the ordinary mop.

Another object is-to provide a mop, the head or mopping element of which may be readily renewed by an inexperienced person, and which is constructed to preclude its losing its shape or symmetry, and which when in operation presents a solid mopping surface thereby adapting itfor use in scrubbing as well as mopping.

Another object is to provide a mop of this character in which the head is so mounted on the frame as to prevent all possibility of scratching'the floor or furni- Another object is to provide a mop of this character composed of few parts and including a frame having a cylindrical hand grip molded integral therewith; and which is strong and free of any attachments such as would be likely to get out of order.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention. 1 c

JOSEPH B. TAYLOR, OF ALLENDALE, NEW JERSEY.

DUST SEPARATOB.

Application filed November 3, 1921. Serial No. 512,527.

To all whom it may concern:

Be it known that I, Josnrn B. Terror, a citizen of the United States, residing in Allendale, county of Bergen, State of New Jersey, have invented Certain new and useful Improvements in Dust Separators, of

a specification.

The present invention has relation to a compact, novel and efficient apparatus for separating solid particles held in suspension in a fiuid; and more particularl to an improved means for separating ust, smoke and fumes from air and other gases.

My improved apparatus operates, broad- 1y speaking, upon the principle of pr0 ecting gases at a high velocity against collecting surfaces so as to cause the suspended dust to stick to the surface, building up to form ridges or buttons. This principle is preferably embodied in apparatus so constructed as to utilize centrifugal force as well as the sticking due to impact. Concave perforated receiving surfaces are preferably em loyed, which are backed up by dead air cl iambers, and it is preferred, also, to cause the air to be diverted from one surface to another (whether perforated or not 'l he apparatus is simple and inexpensive, takes, up little room and may be made very light; It is preferably formed of separable and similar units which can be so used as to build up a complete separating apparatus whose component parts are capable of mutual adjustment with regard to the particular conditions tobe met in each case.

.For the sake of brevity, the following specification will be limited to the descri tion of means for separating dust, smol e or fumes from air or other gases; but the invention is not limited to ap aratus for this purpose, since it may also e used for separating solids in suspension in liquids. Accordingly the expression dead air space and the like is to be understood as a convenient expression covering a space containing any fluid (liquid or gas) in a quiescent condition.

A preferred embodiment of-the invention is illustrated in the accompanyin drawings, wherein Figure 1 is a top p an view of the entire apparatus, Figure 2 is a side elevation of the same showing a part of one wall broken away, Figure 3 is a plan view of one end showing" the top or cover removed, Figure 4 isa sectional view taken on the line &4 in Figure 3, and Figure 5 is a partial diagrammatic view of a modification.

The dust separator proper is enclosed within an uter casing 10 set over a dust hopper 11, hrough which the dust is finally carried off, and suitable doors, 12 and 13, operated by handles 14: or the like, serve as a floor for the primary dust-receiving chamber. By opening these doors momen tarily from time to time, the dust collected above them is allowed to drop into the hopper.

The separator proper is divided into two parts by a perforated floor 15 which supports the separating units in the separating and two complete boxes alternately. The

}groups having only two complete boxes ave half boxes at each end to fill up the width of the separating chamber. Any desired number of transversely arranged groups may thus be employed, the separat- 1ng chamber being correspondingly lon These groups, being independent can be a justed in regard to their relative position to suit conditions.

Each separating box comprisestwo deadair chambers 17 and 18 (see Figure 3) separated by an internal imperforate partition 19. The rear of each chamber 17 and the front of each chamber 18 is enclosed by a cylindrical wall 20, 21, respectively. These walls are concave outward and are perforated, preferably being made of thin metal with short horizontal slits as shown at the left in Figure 4.

The'arrangement thus described is such that the front end of each air passage 16 is directly opposite the middle of a perforated wall 20.

The dust-laden air, coming in at the rear end of the apparatus through a pyramidal distributing passage 22, first enters a vestibule 23 over one end of the perforated floor 15, and strikes a cross partition 24. Wedge-shaped air passages 25 extended forward within this partition and direct the air currents against the walls 20 of the first separating boxes. The coarser particles of dust will be largely arrested within the vestibule 23, dropping through the openings in the floor 15 into the primary dust-receiving chamber. The remainder of the dust will pass through the passages25 and will strike the concave walls 20. Part of this dust will stick to the solid parts of the wall 20, a part will pass: directly through the perforations and will stick to the inner partitions 19, and a part will be separated by centrifugal force from the sharply diverted air stream, passing through the perforations in the walls 20, and falling to the bottom and through the floor 15.

The air, after striking each wall 20 will be sharply diverted by the concavity of each wall, so as to flow back against the front face of the partition 24. Here a part of the dust will stick, while the remainder will flow forward with the air through the first set of passages 16.

As the air emerges from these passages it will lose a further proportion of the suspended dust by a repetition of the proc ess just described, in each case being sharply diverted backward against a collccting element. Instead of a partition as 24, being the collecting elements, however, I prefer to employ dead air chambers 18, as already described; so that the dust will be collected partly by sticking and partly by centrifugal force in the forwardly facing elements, as already described with respect to the rearwardly facing elements. In its broadest aspect, however, the invention comprises the use of collecting elements which divert and reverse the air currents in the manner described, whatever the nature of these elements. It'is quite within the scope of the invention to make all the collecting walls iinperforate.

The dust which sticks to the various surfaces of the apparatus described can be easily dislodged from time to time by percussion, and will fall through the perforations in the floor 15. In order to revent the air from passing down through t e perforations between two sets of separating elements and upward through the floor to elements further on, partitions 26 are used, which divide the primary dust-receiving chamber into a succession of dead air chambers. These partitions extend across the device immediately under the partition 24 and the successive partitions 19.

When the air has passed all the separating elements, it emerges, preferably through the to the details herein shown and described."

Vhat I claim is 1. The process of separating dry dust from a gas in which it is held in suspension which consists in causingsaid dust to collect in a pile upon a dry collecting surface by driving the dust laden gas in a rapid concentrated stream against such collecting plate in a direction substantially normal to said plate. v

In a dust separator, a group of outwardly concave dead air boxes having out amet wardly concave perforated walls placed side by side and separated by air passages; in combination with a second similar group of boxes and air passages so placed that the passages of one group terminate opposite the concave wall of the next group. i

11. Apparatus as in claim 10 wherein the successive groups of boxes are made adjust able with relation to each other 12. The process for separating-dry dust from gases which consists in projecting the vgas to be treated in a localized stream against a receiving surface at such a velocity as to cause the dry dust to adhere and buildup in a pile opposite the point of projection.

13. A dust separator comprising oppositely facing rows of dustcollecting walls placed side by side, all of the walls of one row being concave toward those in the other, the walls of one row being laterally displaced with respect to those in the other, and the walls in one row at least being perforated, dead air chambers behind the perforated walls, and passages between the walls in one row adapted to direct air currents against substantially the middle of the walls in the other row.
